I asked: >>> dd if=foo.verilab.com._.1 bs=32k skip=1 | tar tfv - | sort +2nr | head >>> >>>What if, instead, my dump blob is "chunked", as in this case (1GB chunks):
Alexander Jolk suggested (one of two possibilities): >> Well, you either do some shell magic: >> for i in foo.verilab.com._.1*; do dd if=$i bs=32k skip=1; done | tar tvf ... Gerhard den Hollander followed on with: > or simply > > cat foo.verilab.com._.1* | dd bs=32k skip=1 | tar tfv - | sort +2nr | head Alexander's solution definitely works. Gerhard's solution may do something sensible, but I would classify it as "wrong" -- sorry :-( If each chunk has an Amanda header on it (as it appears it does), then you need something like Alexander's solution to strip them off. With Gerhard's solution, I get ... % cat *.0* | dd bs=32k skip=1 | tar tfv - | sort +2nr tar: Skipping to next header tar: Skipping to next header ... etc... ... which means 'tar' is having to do some guesswork, which I don't like. The results I'm seeing on my sample run suggest it is *not* "skipping" to the right place; i.e. the results are wrong. The Jolk way is the best way! Thanks for the useful thoughts, Will
